SnippetWindow: Hooked up Debugger calls/events.

The Debugger interface is now how the application interacts with the debug session.
A 'Resume' button has been introduced. This replaces the 'RunUT' button during an active debug session.
'RunUT' button is now a 'Step' debugger command during a debug session.
